Abstract

The chronic autoimmune illness known as systemic lupus erythematosus (SLE) is typified by tissue destruction in multiple organs and systemic inflammation. Diagnosing this condition might be difficult because of its varied and fluctuating clinical symptoms. The goal of this research is to use clinical and laboratory data to create a classification model for SLE diagnosis using the Naïve Bayes approach. Age, gender, clinical symptoms, and the outcomes of laboratory tests are among the information gathered for this study. This approach is crucial for helping with SLE management and early diagnosis. The Naïve Bayes model was used to assess and categorize these data according to the severity of the condition. The accuracy, precision, and recall measures were used in the study to evaluate the Naïve Bayes model. The outcomes demonstrated how well the Naïve Bayes algorithm can categorize SLE patients.

Abstract

This project aims to develop an expert system to support agricultural water management using Fuzzy Logic and Rule-Based Decision Making methods. This system is important for improving agricultural yields and environmental sustainability, especially with the increasing demand for food and the impacts of climate change. Data was taken from Kaggle, including information on soil conditions, temperature, and rainfall. Data processing includes missing value removal, outlier detection, and splitting the data into 80% training and 20% testing. Fuzzy Logic was chosen because it is able to handle data uncertainty and provide accurate output regarding crop water requirements, while Rule-Based Decision Making utilizes expert knowledge-based rules for decision making. Simulation results show that the Fuzzy Logic model provides recommendations for water needs according to actual conditions, with high responsiveness to soil moisture and temperature. The system is expected to be a tool to assist farmers in decision-making, increase agricultural productivity, and support water sustainability. This research contributes to the development of expert systems in agriculture and natural resource management based on modern technology.

Abstract

The profession of being a female sex worker carries various forms of risks that encompass physical, sexual, and social aspects. Engaging in this work over a long period is a process filled with courage, self-reflection, and complex dynamics of changing life perspectives. Nevertheless, many of them still have hopes and determination to improve their lives for the better. This study focuses on efforts to understand the relationship between problem-focused coping and social support with life meaningfulness among female sex workers. The research approach used is quantitative with a multiple correlation analysis model. From a total population of 232 people, 44 respondents were selected as the research sample. The research instruments included measures of problem-focused coping, social support, and life meaningfulness, which were analyzed using multiple correlation techniques. The results showed that the first hypothesis could not be tested because the data did not meet the normality assumption. Meanwhile, the second hypothesis indicated a negative relationship between problem-focused coping and life meaningfulness, whereas the third hypothesis found a positive relationship between social support and life meaningfulness. These findings suggest that the greater the social support received, the higher the level of life meaningfulness experienced by female sex workers.
